Intermittent Fault.
For a long time I have been suffering with an intermittent fault with my broadband signal. Coming into the house the signal is good. Using my WiFi the signal is transferred from upstairs where it comes into the house to my 360 box downstairs. For 90% of the time this works very well with a high signal strength without any problems. However every few days I lose the signal strength for a couple of hours at a time. Having previously tried switching things off and on without making any difference and have discovered that if I do nothing after a couple of hours the system comes back up and everything is running normally.
I suspect that something is interfering with the signal from upstairs reaching downstairs and yesterday I contacted Virgin and asked if they could tell me what devices were now using the WiFi. They claimed that they were unable to do this despite that a week earlier when trying to resolve the problem the agent was able to tell me what devices were on the system. I have tried in vain to speak to a qualified technician who might be able to explain a likely cause of the problem. Instead they have sent a new router for me to install but I am somewhat reluctant to do this without first understanding the problem.
At the moment everything is working perfectly and I wondered if anyone has had a similar problem and if so how it was resolved.
